Method for orange preservation

Abstract

The invention discloses a method for orange preservation, and belongs to the field of fruit preservation. The method comprises the following steps: performing ultrasonic extraction on Chinese herbal medicines, such as leaf of purple perilla, and concentrating, so as to obtain a concentrated solution containing natural antiseptic organic matter, such as fat and phenols, taking rice and rice polishing as carriers, feeding the concentrated solution into the rice, so as to be soaked, drying and grinding the rice, mixing the rice with the rice polishing, ensuring that effective components in the Chinese herbal medicines are absorbed on the surfaces of the rice and the rice polishing, ensuring that organic components in the rice and the rice polishing are infiltrated into the interior of an orange peel under the roast smoking action of roasted wood charcoal, and ensuring that a layer of dense membrane is formed between the inner membrane layer of the orange peel and flesh, so as to isolate the external air and achieve the purpose of orange preservation. The method effectively solves the problems that the traditional method is poor in preservation effect and toxic substance is easy to remain, and the method is safe and environmental-friendly, does not have poisonous substance residue, is not harm to human health, and has good preservation effect.

Problems solved by technology

[0004] The technical problem to be solved by the present invention: Aiming at the disadvantages of poor fresh-keeping effect and easy residue of toxic substances in the current orange preservation method, a method of ultrasonically extracting Chinese herbal medicines such as perilla leaves and concentrating them to contain natural antiseptic organic substances such as oils and phenols is provided. The concentrated solution, with rice and fine rice bran as the carrier, the concentrated solution is added to the rice for soaking, dried and milled, mixed with the treated fine rice bran, so that the active ingredients in the Chinese herbal medicine are adsorbed on the surface of the rice and fine rice bran, after roasting Under the action of charcoal smoking, the organic components in the rice and fine rice bran penetrate into the orange peel, forming a dense film between the inner membrane layer of the orange peel and the pulp to isolate the outside air, so as to achieve the purpose of keeping the orange fresh. It effectively solves the problem of poor fresh-keeping effect and easy residue of toxic substances in traditional methods. The invention is safe and environmentally friendly, has no toxic substance residue, has no harm to human health, and has a good fresh-keeping effect
